JSONP简单示例

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>无标题页</title>
     <script type="text/javascript">
         var script = document.createElement("script");
         script.type = "text/javascript";
         script.src = "IbeaconHandler.ashx?op=callBack";
         document.getElementsByTagName("head")[0].appendChild(script);
         //回调函数
         function callBack(jsonp) {
             alert(jsonp.name); //judy
         }
    </script>
</head>
<body>
</body>
</html>

后台代码：

<%@ WebHandler Language="C#" Class="IbeaconHandler" %>

using System;

using System.Web;

public class IbeaconHandler : IHttpHandler {

    public void ProcessRequest (HttpContext context) {

        context.Response.ContentType = "text/plain";

        string fname = context.Request.QueryString["op"].ToString();

        string str =fname+"({name:'judy',age:'23'})";

        context.Response.Write(str);

    }

    public bool IsReusable {

        get {

            return false;

        }

    }

}
